Hello all...

I want to transfer data(just glow a light) in serial
port or parallel port...

parallel port as follows:

#include "asm/io.h"
#include<unistd.h>
#include<stdlib.h>
#include<stdio.h>
main()
{
outb(0x378,0xff);
printf("Data sent out \n");
}
----------------------------------------
but when i compiled,it showing errors as follows:
[root at mail root]# powerpc-linux-gcc out.c
/tmp/ccED5Jlo.o: In function `main':
/tmp/ccED5Jlo.o(.text+0x20): undefined reference to
`outb'
/tmp/ccED5Jlo.o(.text+0x20): relocation truncated to
fit: R_PPC_REL24 outb
collect2: ld returned 1 exit status
[root at mail root]#
----------------------------------------
the oub function defination is in "asm/io.h"..which
